Abstract
Abstract A seat for a motor vehicle, the back rest of which is adjustable to different substantially sinusoidal curvatures by turning a single hand wheel. If the back rest carries a head support, an adjustment of the shape of the back rest also causes the position of the head support to be shifted forwardly or rearwardly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
277 words
A seat having a seat part and a back rest, said back rest comprising a substantially rigid frame having substantially horizontal upper and lower frame members and lateral frame members connecting said upper and lower frame members to each other, a padding support divided into an upper part and a lower part, upper pivot means for pivotably connecting said upper part near its upper end to said upper frame member, and lower pivot means for pivotably connecting said lower part near its lower end to said lower frame member, said upper and lower pivot means having substantially horizontal axes, adjusting means for pivoting said two parts to different positions relative to each other about said upper and lower axes and for maintaining said two parts in each of said positions, and padding means connected to one side of said two parts, said two parts of said padding support consist of two substantially rigid plates, and flexible means connecting said plates to each other at their edges facing each other, said two plates are curved in opposite directions to each other and said flexible means pivotably connect said edges of said plates to each other, said adjusting means being adapted to act upon one of said plates adjacent to said edges to pivot both of said plates simultaneously in opposite directions about said axes, said pivot means on one of said parts also being slidably connected to one of said horizontal frame members so as to be slidable substantially in the direction of said lateral frame members when said plates are being adjusted by said adjusting means from one position to a different position relative to each other.
Claim 2
Dependent Claim
277 words
A seat having a seat part and a back rest, said back rest comprising a substantially rigid frame having substantially horizontal upper and lower frame members and lateral frame members connecting said upper and lower frame members to each other, a padding support divided into an upper part and a lower part, upper pivot means for pivotably connecting said upper part near its upper end to said upper frame member, and lower pivot means for pivotably connecting said lower part near its lower end to said lower frame member, said upper and lower pivot means having substantially horizontal axes, adjusting means for pivoting said two parts to different positions relative to each other about said upper and lower axes and for maintaining said two parts in each of said positions, and padding means connected to one side of said two parts, said two parts of said padding support consist of two substantially rigid plates, and flexible means connecting said plates to each other at their edges facing each other, said two plates are curved in opposite directions to each other and said flexible means pivotably connect said edges of said plates to each other, said adjusting means being adapted to act upon one of said plates adjacent to said edges to pivot both of said plates simultaneously in opposite directions about said axes, said pivot means on one of said parts also being slidably connected to one of said horizontal frame members so as to be slidable substantially in the direction of said lateral frame members when said plates are being adjusted by said adjusting means from one position to a different position relative to each other.
Claim 3
Dependent Claim
68 words
A seat as defined in claim 1, in which, when said back rest is seen from the front, said upper plate has a convex curvature and said lower plate has a convex curvature, said flexible means connecting said edges of said two plates forming at least one hinge having a substantially horizontal axis, said plates when seen in a side view together having a continuous substantially sinusoidal curvature.
Claim 4
Dependent Claim
61 words
A seat as defined in claim 1, in which said upper pivot means comprise at least one hinge, and said lower pivot means comprise means for connecting the lower end of said lower plate to said lower frame member so as to be pivotable about a horizontal axis as well as slidable substantially in the direction of said lateral frame members.
Claim 5
Dependent Claim
71 words
A seat as defined in claim 1, in which said adjusting means comprise gear means, a manipulating member mounted on one of said lateral frame members and rotatable about its axis for turning said gear means and an eccentric member connected to said gear means and extending eccentrically to said last mentioned axis and adapted to act upon the rear side of one of said plates near said flexible connecting means.
Claim 6
Dependent Claim
53 words
A seat as defined in claim 4, in which said gear means are adapted to be turned by said manipulating member so as to turn said eccentric member, said gear means incapable of being turned by said eccentric member when a pressure is exerted by one of said plates upon said eccentric member.
Claim 7
Dependent Claim
60 words
A seat as defined in claim 1, further comprising means for securing a head support to said upper part of said padding support so that, when said upper part is pivoted to a different position by said adjusting means, said head support will also be pivoted to a different position relative to the head of an occupant of said seat.
